Since the 70s, scientists have progressively attempted to recreate
the human immune system’s most powerful disease fighting mechanism: first
through animal and chimeric hybridization and then humanized and recombinant
forms.

All of these methods had shortcomings through immune system rejection,
toxicity, prohibitive costs, or limited antibody diversity.

Previous Limitations to Natural Human Antibody Discovery

1. Limited Lifespan of Antibody-Producing Cells Outside Body

2. Memory B Cell Rarity (0.001% of blood cells)

3. Signal among the noise - finding the most effective, relevant antibodies

Requires High Speed

Requires High Throughput

Requires High Resolution

How Our CellSpot Technology Works

CellSpot was designed to address previous limitations to native antibody discovery, chiefly the low frequency of useful antibodies against specific disease targets among millions of irrelevant antibodies; the short lifetime of human B-cells outside the body; and the challenge of efficiently cloning from single cells.
